I can’t fault the flasks or the cups
I can’t fault the flasks or the cups, I find if I use ice everything keeps cold for way longer than they state which is brilliant. I would love to be able to buy stoppers for the straws in a matching colour to the cup. The only negative I can find for the Newt is I would like the hole to be wider to fit larger ice cubes in. I don’t know but maybe the hole has to be that size for when having fizzy drinks in it?
